y ASH SIFTER AND RECEPTACLE.

, SPECIFICATION forming part of Letters I Patent No. 593,838, dated November 16, 1897.

Application filed February 4,1897. Serial No. 621,950. (No model.) y

To @ZZ whom it may concern.-

Be it known that I, RICHARD EVANS, a citizen of the United States, residing at Milwaukee, in the county of Milwaukee and State of Wisconsin, have invented new and useful Improvements in Ash Sitters and Receptacles, of which the following is a specification.

My invention relates to improvements in ash sifters and receptacles.

The object of myinventionis twofold: first, to provide an ash-receptacle into which ashes may be deposited, a shovelfulat a time, direct from a furnace or other heating apparatus without the usual annoyance from dust which is raised as the ashes are discharged from the shovel; second, to provide a device by which theunburned coal remaining in the ashes will be automatically screened out and separated from the ashes as the same are depositedin the receptacle and the coal and ashes deposited into two separate receptacles l provided therefor.

The construction of my invention is further explained by reference to the accompanying drawings, in which- Figure 1 represents a front view of-my device, part in section. Fig. 2 represents an end View with a part broken away to show the interior mechanism for operating the doors and cover, and Fig. 3 represents a'vertical section.

Like parts are referred to throughout the several views by the same reference-letters.

A represents the ash-receptacleproper.

B is an ordinary ash-screen, upon which the ashes are deposited a shovelful at a time, when, owing to its inclined position, the ashes and coal mixed therewith are caused to flow of their own gravity downward -ver the screen, whereby the ashes are sifted outl and pass down into the ash box or drawer C, while the coal and other coarser substances are discharged into the coal box or drawer D.

To prevent the dust from rising as the ashes are discharged from the shovel, a shovel-inclosing cover E is provided, which is caused to automatically close above and around the shovel as soon as it is brought into position to be emptied, while the folding doors F and G simultaneously open below the shovel to permit the contents of the shovel to pass them.

The doors and cover are thus automatically actuated by the weight of the shovel and its contents resting upon the standard H,where by saidl standard is pressed downward with its supporting-spring I,when it communicates the required movement to said doors and cover, as described. When the shovel has been thus emptied and its weight removed from the supporting-standard H, said doors and cover are automatically moved in the opposite direction, whereby the dust arising from the falling ashes is shut in by the closing of the doors F and G, while the cover E is thrown back preparatory to removing the shovel. Motion is communicated from the shovel-supporting standard H as the shovel is placed thereon to the cover E through the barJ, link K, pivotal bolts L L', segmental pulley M, shaft R, cord N, segmental pulley O, and shaft P, whereby said cover is closed, while motion is simultaneously communicated from such standard H to the folding doors F and G through the said bar J, links K and K', segmental pulley M, arm M', and

shafts R and R', to which shafts R and R' said folding doors are respectively secured. When the ashes have been discharged and said standard relieved from the weight of the shovel, said standard is thrown upward by the recoil of the spring I, when the coverEis thrown open by the action of the spring S or other equivalent device. The spring S is at* tached at one end to the cover E and at its opposite end to the side of the receptacle B'. When said cover E is thrown open, as described, motion is communicated from said standard H to said folding doors through the connecting mechanism previously described, and said doors are thereby closed. The cover E is rigidly secured to the shaftPof the segmental pulley O,whereby said cover is opened and closed as said pulley is turned upward and downward. The cover-supporting shaft P and the door-supporting shafts R and R' are respectively supported at their respective ends in apertures provided therefor in the end walls of their respective inclosures, as shown.

When using an ash-box of less width than the screen above, as shown, I preferably locate a catch-board A' below the upper portion IOO of the screen by which the ashes from such upper portion of the screen are conducted forward to and deposited into the ash-box.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. In an ash-receptacle, the combination with the inclosing walls thereof of a slanting screen arranged at an angle to the vertical walls of the inclosure; a shovel-supporting standard located above said screen; a shovelinclosing cover pivoted to the upper inclosing walls of said receptacle upon a supportingshaft; mechanism for automatically swinging open said cover upon its supporting-shaft; and mechanism for communicating motion from said shovel-supporting standard to said cover, and automatically closing the same as the weight of a shovel and contents is supported thereon, whereby said cover is automatically closed above the shovel and its contents, and the dust therefrom, when emptied, is prevented from rising, substantially as and for the purpose specified.

2. In an ash-receptacle, the combination with the inclosing walls thereof of a slanting screen arranged at an angle to the vertical walls of the inclosure; a shovel-supporting standard located above said screen; a shovelinclosing cover pivoted to the upper inclosing walls of said receptacle upon a supportingshaft; mechanism for automatically Swingin g open said cover upon its supporting-shaft; mechanism for communicating motion from said shovel-supporting standard to said cover, and automatically closing Jthe same as the weight of a shovel and content-s is supported thereon; swinging doors located beneath thc upper inclosing walls of said receptacle adapted to close above the ashes after they have been discharged upon said supporting-screen; and mechanism for communicating motion from said shovel-supportin g standard to said swinging doors, substantially as and for the purpose specified.

3. In an ash-receptacle, the combination within the inclosin g walls thereof of a slanting screen B, arranged at an angle to the vertical walls of the inclosure; a shovel-supporting standard H located above said screen; standard-supporting spring I adapted to retain said standard H in its raised position when the shovel-inclosing cover is thrown open; shovel-inclosing cover E pivoted to the inclosing walls of the receptacle upon a supporting-shaft P, having bearings in the respective ends of its inclosing walls; bar J rigidly alixed to the supporting-standard H and connected at one end with said shovel-inclos.- ing cover E through the pivot L, link K, pivot L, segmental pulley M, cord N, segmental pulley O and cover-supporting shaft P, whereby said cover E is closed by the downward movement of said standard II; spring S secured at one end to said cover E and at its opposite end to the receptacle B, and adapted byits recoil to swing back and open said cover as soon as the standard I-I is relieved from the weight of the shovel thereon, said bar J being connected with the respective doors F and G through the links K and K', segmental pulley M and arm M', pivots L, L and L', L', and door-supporting shafts R and R, all substantially as and'for the purpose specified.

In testimony whereof I aiix my signature in the presence of two witnesses.

RICHARD EVANS.
